Puppet: 4.2.1
OS: RHEL/Centos 7 (can also simulate on Windows if I set osfamily to
'RedHat')
Most of the time I develop Puppet modules to run only on Windows but
sometimes I want them to be able usable on other OS's particularly RHEL.
Sometimes there's a choice between adding a bunch of predicates to a
manifest to detect the current OS and just maintaining separate manifests.
Notwithstanding the argumant for or against, in this particular case I
decided to follow the latter and encountered a problem I haven't seen
before.
Specifically it *appears* that using the OSFAMILY name as part of a class
name[space] causes an error. Or more precisely, since I have already used
this approach successfully with 'windows' being part of a class namespace,
an error occurs if I use 'RedHat'.
Example:
docker_registry_host/manifests/init.pp :-
class docker_registry_host {
...
notice('CLASS: docker_registry_host')
notice('---------------------------')
notice("osfamily = ${::osfamily}")
...
include "::docker_registry_host::${::osfamily}::install"
...
}
docker_registry_host/manifests/RedHat/install.pp :-
class docker_registry_host::RedHat::install {
notice('CLASS: docker_registry_host::RedHat::install')
notice('--------------------------------------------')
}
Produces this error (full stack trace below) :-
Notice: Scope(Class[Docker_registry_host]): CLASS: docker_registry_host
Notice: Scope(Class[Docker_registry_host]): ---------------------------
Notice: Scope(Class[Docker_registry_host]):
Notice: Scope(Class[Docker_registry_host]): osfamily = RedHat
Debug: importing
'E:/Data/git/docker_registry/puppet/environments/production/modules/docker_registry_host/manifests/RedHat/install.pp'
in environment production
Error: Illegal fully qualified class reference at
E:/Data/git/docker_registry/puppet/environments/production/modules/docker_registry_host/manifests/RedHat/install.pp:4:38

`_racc_yyparse_c'
C:/Apps/puppet/sys/ruby/lib/ruby/2.1.0/racc/parser.rb:319:in `yyparse'
...
So no problem finding the docker_registry_host::RedHat::install class, but
also ... Error: Illegal fully qualified class reference ??
If I change that part of the class namespace 'foo' everything works fine :-
... so in init.pp if I use :-
include "::docker_registry_host::foo::install"
and have the class : docker_registry_host/manifests/foo/install.pp :-
class docker_registry_host::foo::install {
notice('CLASS: docker_registry_host::foo::install')
notice('--------------------------------------------')
notice('')
}
Output as expected and no error at all.
As I mentioned above, I have used include and contain statements with
${::osfamily} in them many times before when the osfamily value resolves to
'windows'. For example in another module I have an install class called :-
class sonatype_nexus::windows::install {
.. and it works just fine.
So I guess I'm wondering why this error occurs when osfamily resolves to
'RedHat'.
In case it makes a difference, when I'm testing locally I'm using Centos
rather than full-blown RHEL but running 'facter osfamily' still returns
'RedHat'
Any ideas why this is happening (is 'RedHat' illegal in a class name[space]
or a reserved word, or ...) ?
Kind Regards
Fraser.
